Pretty much in the same boat! Granted, I know there are a lot on GAF that are international players, so their MM pool might not be so great or robus.
The pool of players ain't the cause of slow matchmaking.
Even if there were only 3 people playing online worldwide, two of them would fight each other, and the third one should only wait, at most, the time the first two took to fight each other.
The waiting times for matchmaking are way longer than that.
